Manufacturing Process

1

Raw Material: Rod or wire inspection via metallurgical testing.

2

Heading: Raw material fed through high-speed headers to form rough spheres.

3

Flashing: Cleaning up headed balls for a smoother appearance.

4

Heat Treatment: Hardening the balls in industrial ovens at extreme temperatures.

5

Grinding: Precision grinding to approximate final sphere size.

6

Lapping: Final forming to meet exact grade tolerance limits.

7

Final Inspection: QC department testing for size, roundness, and surface finish.
